1. Introduction

This manual is the reference when setting up the InduBox GSM IX modem for yourapplication. Because of the nature of this product and it's field of application, somedegree of technical background knowledge regarding the application and data-communication is assumed.

The InduBox GSM IX modem is a versatile communication device designed to providea very flexible data communication solution for an industrial environment. The InduBoxGSM IX modem contains a number of options to accommodate different communicationspeeds, power supplies and interfaces.

The InduBox GSM IX is designed to transmit and receive –transparent- ASCII formatteddata on a GSM data channel. Communication between the InduBox GSM IX and a DTErange from 300 to 115.200 bps. With the GPRS/UMTS option and embedded TCP/IPstack, data can be send/received into a TCP/UDP socket to and from a remote socketserver.

Besides serial communication using standard RS-232, other galvanically and logicallyseparated interfaces are available like RS-232 3-wire and RS-485 3-wire.

Besides a periodical (hard) reset, configurable between 1 and 168 hour, an externalmodem reset is possible via the additional 'V+'-connection to ensure a proper modemworking.

The InduBox GSM IX is designed in a robust housing with different power supplyoptions accepting a wide range of AC voltages.


2. Block Diagram

The block diagram below details the location and interconnection of the differentfunctional units within the modem. The most important units are briefly described.

AC/DC power supply The mains supply (ac) must be connected to the InduBox GSM IX modem via a 2 pinterminal block with screw contacts. Make sure the voltage supplied to the modem is inthe range of the InduBox GSM IX input voltage (see specifications for details onvoltage range).

Long Term Watchdog A long term watchdog circuit is implemented. The modem will perform a reset each 1 to168 hour (configurable) and/or if necessary via the external '+V'-connection to preventa lock-up. The power supply of the GSM/GPRS module will be disconnected for a fewseconds after the reset period. A ‘heartbeat’-LED is implemented to check the long termwatchdog.


Switched regulator To create the necessary dc-voltage (Vgsm) to power the GSM/GPRS module a 2A stepdown switching regulator is implemented.

Configuration InterfaceThe InduBox GSM IX modem has one complete (TxD, RxD, DCD, DTR, RTS, CTS, RIand GND) RS-232 interface. This RS-232 interface is not isolated and must be used toconfigure and/or update the Sierra Wireless (Wavecom) GSM/GPRS module. Thisinterface has a RJ-45 connector.

Isolated DTE interfaces The InduBox GSM IX has 2 galvanically isolated serial interfaces :

3- wire RS-232 (RxD, TxD, GND’) :

This interface is connected (galvanically separated) to the UART1 of the SL6087GSM/GPRS module. V' - pin can be used for external reset (V') or for powering (100 mA Imax) an externaldevice (+5V'), selectable via resistor stuffing.

3- wire RS-485 (A, B, GND’) :

This interface is connected (galvanically separated) to the UART2 of the SL6087GSM/GPRS module.

V' - pin can be used for external reset (V') or for powering (100 mA Imax) an externaldevice (+5V'), selectable via resistor stuffing.

V.24 Status LED’s The V.24 lines to and from the UART1 GSM/GPRS module have a LED indicator.

8. Watchdog Functionality

To prevent a “total lock-up” of the InduBox GSM IX a long term watchdog isimplemented. This function is created with a separate micro-controller. The micro-controller itself is guarded with it’s own internal watchdog (+/- 1 secondrefresh / LED flash).

This long term watchdog has 2 possible ways to reset the modem :1. configurable periodically reset2. external reset triggered by the '+V'-connection (JP6 and/or 7 on 'Meter' position)

8.1 Periodical reset

The power supply will be disconnected, after a controlled and proper GSMdisconnection, during 20 seconds after the selected reset period IF the modem is NOTconnected (inactive DCD signal).

If the reset period is ended and the modem is connected to a remote host (active DCDsignal) the reset will not be conducted. If the reset period is ended + 10 minutes andthe watchdog already past a reset, because of an active DCD signal, the reset will beconducted! Otherwise, the InduBox GSM IX can be “locked-up” with an active DCDsignal the watchdog will never be able to reset the WAN module.

Time is programmable via the serial setup menu of the modem.This menu is accessible via the RJ-45 serial interface (9600 bps 8N1) after hitting theblue push 'switch' located next to the reset processor onto the modem printed circuitboard.

| -- START --|| Bausch Datacom InduBox GSM IX setup [V1.0]|| Reset period time select [currently 24 hour]| Do you want to change this [y/n] :

Enter 'y' if you want to change the default 24 hour to another value.The new value will automatically be stored in non volatile RAM.

Select 0 hour to disable this hardware reset to use the software reset generated fromthe SL6087 module, if provided by an OpenAT application.

8.2 External reset

The power supply will be disconnected, after a controlled and proper GSMdisconnection, during 20 seconds when a negative slope (5-25V to 0V) is detected onthe '+V'-input.

There is no DCD check done in this reset mode. InduBox GSM IX Manual with Socket Server Open AT® application Version 2.0b 20/34

9. AT Command Interface

More information about the commands to the InduBox GSM IX modem, and theresponses from the InduBox GSM IX modem, are described in the Sierra Wireless(Wavecom) reference manual ‘AT commands interface guide’.

9.1 Most important AT commands

Verifying GSM receive signal quality

The modem will be able to establish a call only if the received GSM signal is of a sufficient

level.

The command AT+CSQ will return the reception level <rssi> of the signal sent by theclosest GSM Base Transceiver Station (BTS), as well the received bit error rate <ber>.When the SIM card is present and the PIN code has been entered, the commandAT+CSQ will return the signal level from the BTS on the subscribed operator network.When used without the SIM card, this command will simply indicate the closest BTSdue to the fact that the modem cannot identify the current subscription. It is thereforeadvisable to make this test with the SIM card present.

To verify the GSM signal quality, perform the following operations:Using a communication application, enter the command AT+CSQ.

The response is in the following format:

+CSQ: <rssi>,<ber> where...

rssi indicates the reception level (Received Signal. Strength Indication).ber indicates the received bit error rate (Bit Error Rate).

How to interpret the results :

The InduBox GSM IX functions correctly with a minimum <rssi> of between 12 and 15.Below 10 the signal is insufficient, the modem cannot function depending on the geo-graphical situation. Above 15 the signal is of a sufficient level.

The InduBox GSM IX functions also correctly with a ‘ber’ = 0.

PIN-code

The PIN code is essential in order to make a call or to accept a call from the GSM net-work. The PIN code is held on the SIM card and can be modified by the user.

To verify a previously entered PIN code or see if the SIM card is working properly, usea communication application and enter the command AT+CPIN.

(Ensure that a valid SIM card is present in the SIM card reader in the modem)


Verify a PIN code and see if the SIM card is working properly

AT+CPIN?The InduBox GSM IX must return:+CPIN : READY

AT+CFUN

Do not simply cut off the supply of the InduBox GSM IX modem whilst in communicationor dialogue without having first detached from the network operator.To avoid network congestion when powering down the modem, it is essential to firstexecute the command AT+CFUN=0.If this is not done, then, in certain cases the modem can remain registered on the net-work.

When you want to power down (‘hard’ reset) the unit which is in dialog mode and not incommunication or you want to do a 'warm' reset:

AT+CFUN=0OKThe modem will return OK and is no longer registered on the network. The SL6087 GSM/GPRS radio module is put into standby and the power may then be removed.

AT+CFUN=1OKThe InduBox GSM IX will perform a 'warm' reset.


10 ‘Socket Server’ application in Open AT ®

10.1 Introduction

This manual is the reference manual for configuring the Socket Server Open AT® (1).application.

The Socket Server Open AT® application is created for the Bausch Datacom InduBoxGSM modems (2). The InduBox GSM IX modem is using the Sierra Wireless SL6087GSM/GPRS module.

Thanks to the Socket Server Open AT® application, a non IP enabled device (like anItron SL7000 C&I electricity meter), connected to the Indubox modem, will beaccessible over a GPRS link.

10.2 General Description

CSD (Circuit Switched Data) data communication with GSM modems has a similarbehavior as connections with standard PSTN modems over a POTS (Plain OldTelephone System) line.

In CSD answering mode (auto answer active s0=1), the Indubox modem will sent theunsolicited CONNECT 9600 respons when a successful connection is established witha remote originating modem. When the remote modem is disconnecting the connection,the respons NO CARRIER will be transmitted.

When using GPRS the situation is completely different. TCP/IP is used, all data will besent in packets and routed over an IP packet switched network.

Thanks to the Socket Server Open AT® application a CSD answering mode will besimulated when using communication over a GPRS link.When the Open AT® application is started in SCKserv mode, a GPRS/APN connectionwill be automatically established and maintained. After a successful GPRS/APNconnection the InduBox modem will be part of an IP network (Internet or Intranet) and

(1) The AirPrime SL6087 GSM/GPRS processor is a product of Sierra Wireless (Wavecom). Itfeatures 2G quad-band (850/900/1800/1900 MHZ) connectivity and has industrial features like anextended temperature range (-40°C to +85°C).The SL6087 GSM/GPRS processor integrated in the InduBox GSM IX can be used as a simplemodem controlled via AT commands or it can host a standard ANSI C/C++ application and act asa single processor for the customer solution because it is delivered with the full set of Plug-Ins forOpen AT® OS, enabling Bausch Datacom to easily add TCP/IP and Internet security.Thanks to the Bausch ‘Socket Server’ Open AT® application (embedded in the SL6087processor) the need for an external processor is eliminated and the total size and cost of the finalproduct is reduced.

(2) The Socket Server Open AT® can be used in InduBox GSM IV (Q24PL GSM/GPRS module ofSierra Wireless – Wavecom -), InduBox GSM VII and VIII (Airprime Q2686 GSM/GPRS moduleof Sierra Wireless – Wavecom -), InduBox GSM IX (SL6087 GSM/GPRS module of SierraWireless – Wavecom-), but also on the DinBox GSM/GPRS (Q24PL).


will have an IP number. The Open AT® application will start a TCP socket server(listener) service and will listen to a predefined PORT.

When a remote TCP client establishes a connection with the InduBox modem, theunsolicited respons CONNECT 9600 will be transmitted. When the TCP client isdisconnecting the connection, the respons NO CARRIER will be transmitted.

More information about the different modes of the Socket Server Open AT® applicationare described in the following sections.

10.3 Basic Setup

When using the Socket Server Open AT® application the serial port of the InduBoxmodem can only be used with the following parameters :

Speed : 9600 bpsAsync format : 8N1Flow control : none (no RTS needed from DTE)V.24 DTR signal : none (no DTR needed from DTE)

Basically only RXD/TXD and GND are needed to use the Open AT® application.It’s possible to use the isolated 3-wire RS-232 and 2-wire RS-485 interfaces of theInduBox GSM IX modem.

10.4 Possible Modes

There are 3 possible working modes into the Socket Server Open AT® application :

10.4.1 CSD mode

The modem is acting like a normal GSM CSD data modem in autoanswer mode (s0=1).When a remote modem dials-in the unsolicited respons CONNECT 9600 is sent.When the connection is disconnected NO CARRIER will be sent. During CSD “datamode” the modem is 100% transparent.

During “idle state mode” the modem is able to receive a SMS message and check themessage content. More info on the SMS message content info below.

10.4.2 GPRS mode

Same function as CSD described above, but the modem has received APN GPRSparameters via a SMS message. APN server name, username, password and DNS infois entered, but there is no GPRS attachment or APN connection.

This mode is implemented to allow DOTA (Download Over The Air) upgrade via a FTPhost. This function is described below.InduBox GSM IX Manual with Socket Server Open AT® application Version 2.0b 24/34

During “idle state mode” the modem is able to receive a SMS message and check themessage content. More info on the SMS message content info below.

10.4.3 SCKServ mode

In this mode, the modem will automatically be connected to GPRS/APN and a TCPsocket server (listen) service will be started. The APN connection and the socket listenmode will be checked regularly (60 seconds) so that the modem is always ready for aTCP socket client.

When a remote TCP client establishes a connection with the InduBox modem, theunsolicited respons CONNECT 9600 will be transmitted. When the TCP client isdisconnecting the connection, the respons NO CARRIER will be transmitted.

During “data mode” the modem is 100% transparent.During “idle state mode” the modem is able to receive a SMS message and check themessage content. More info on the SMS message content info below.

10.5 How to switch between the 3 modes via SMS

Switching between the modes described above is done via (text) SMS messages.

Note:· Each line must be terminated with a <CR><LF>, also the last (End) line· Each character is case sensitive.

In a default state CSD mode is selected. No GPRS parameters are saved.

10.5.1 Switch to GPRS mode

A SMS with the following content must be sent to the modem;

InduBox startup.iniLink : GPRSAPN : “proximus.internet.be”APNUN : “username”APNPW : “password”DNS1 : “”DNS2 : “”End

When the modem receives the SMS message as described above, the modem willsave all the received parameters, restart and enter the GPRS mode. As explainedabove; this mode acts the same as CSD but all APN parameters are know andprogrammed. This mode exists to do an FTP upgrade as explained in next chapter.


10.5.2 Switch to SCKserv mode

A SMS with the following content must be sent to the modem;

InduBox startup.iniLink : SCKservAPN : “proximus.internet.be”APNUN : “username”APNPW : “password”DNS1 : “”DNS2 : “”Port : 404End

When the modem receives an SMS message as described above, the modem will saveall the received parameters, restart and enter the SCKserv mode. After the GSMregistration the modem will automatically establish a connection to the GPRS networkand the APN. The received IP address will be sent onto the serial port as an unsolicitedrespons and the socket server service will start automatically.

10.5.3 Switch to CSD mode

It’s always possible to go back to the default CSD mode via the following SMS;

InduBox startup.iniLink : CSDEnd

When the modem receives an SMS message as described above, the modem willrestart, and enter the CSD mode.

10.6 How to switch between the 3 Modes via “at” commands

Switching between the modes described above can also be done locally, via standard“at” commands.

Connect the InduBox GSM IX modem, via the Bausch RJ-45 to DB-9 serial cable, to astandard COM port of a PC. Use a standard serial communication program likeWindows Hyperterminal, configured onto the correct COM port / 9600 bps / 8N1 / noflowcontrol.

Don't change the currect settings of the modem !
